Encrypted file transfer

Safe login with passcode

Create a passcode upon first launch and use your phone number to log into the service. Your passcode is encrypted and there's no tool to hack it. None of your personal data is stored on Sicher servers.

Free chat and media sharing on-the-go

Exchange messages and media for free. No upfront cost, no annoying ads, no subscription fees. Sicher is free and unlimited.

Collaborate and talk in groups

Collaborate on projects with team members and take part in group discussions. Create encrypted chats to discuss issues and share files.

No open data in Push notifications

Push notifications tell you about new messages but don't show what the messages are about. This protects your privacy and makes mobile messaging even more secure.
